MONTHLY REPRINT OF NOTICES TO MARINERS
OF TEMPORARY AND PRELIMINARY NOTICES
IN FORCE AS OF MAY 26, 2017

Geographical positions refer directly to the graduations of the largest scale Canadian Hydrographic chart unless otherwise indicated.

Bearings refer to the true compass and are measured clockwise from 000°(North) clockwise to 360°; those relating to lights are from seaward.

Visibility of lights is that in clear weather.

Depths - The units used for soundings (metres, fathoms or feet) are stated in the title of each chart.

Elevations are normally given above Higher High Water, Large Tides unless otherwise indicated.

EXPLANATION OF TEMPORARY AND PRELIMINARY NOTICES

Certain Notices to Mariners appearing in the monthly editions have a (T) or (P) appended to the regular number. These letters indicate that the information contained in the notice is of a temporary or preliminary nature.

TEMPORARY NOTICES (T)

If a temporary change in conditions affecting navigation exists and if the change will be effective for a period of over three months, a (T) notice will be published. Temporary changes which are effective for periods of less than three months will not normally be published. Such information will be broadcast as Notices to Shipping by the Coast Guard base of the area concerned. (T) notices will be cancelled as necessary.

PRELIMINARY NOTICES (P)

(a) When important changes affecting navigation are to take place in the near future, a Notice to Mariners describing the change will be published so that the mariners will have advanced information on the change. Such notices will be designated (P).

(b) When a change in conditions affecting navigation has taken place but full information is not available, a (P) notice giving available information will be published. This notice will be followed by a regular notice when complete information becomes available. The regular notice will cancel the (P) notice.

(c) When a change has taken place which is too complex to describe in a written notice, a (P) notice giving general information will be published. This notice will explain that follow up action will be taken to update charts by publishing patch corrections, new editions or new charts.

ACTION REQUIRED ON RECEIPT TO (T) & (P) NOTICES

It is not customary to make permanent corrections to charts and publications from (T) and (P) notices. On receipt of such notices, the information they contain should be noted in pencil on the affected charts and/or publications.

CAUTION

Mariners are reminded that charts and publications are not corrected from (T) and (P) notices when purchased from suppliers. Reference should be made to the latest list of charts affected by Temporary and Preliminary Notices published.

Comments on this action are solicited from mariners and other interested parties within three month from the date of this Notice.
Comments should be directed to the following within three months from the date of this notice:

Any objections raised must state the facts on
which they are based and should include supporting
information on safety, commerce and public
benefit.

*809(P) LAC SAINT-LOUIS – RANGE TO BE MODIFIED

Reference Chart: 1430

The Canadian Coast Guard proposes to
permanently replace the following aids to
navigation:

To discontinue the Dixie range lights (LLIW
1201-1202), which operates at night only, and replace
it by a sector light located at position 45° 25’
16.04’’N 073° 44’ 45.02’’W. This new sector light
would have a nominal range of 5 nautical
miles.

The arcs of visibility (true bearing) would be
the following:

Red sector: from 107° to 52°.

White sector: from 52° to 50°.

Green sector: from 50° to 264°.

This change would be effective in the spring of
2016.

Comments on this action are solicited from
mariners and other interested parties.

Comments should be directed to the following
within three months from the date of this
notice:

Any objections raised must state the facts on
which they are based and should include supporting
information on safety, commerce and public
benefit.

*1005(T) PORT DALHOUSIE - EAST AND WEST PIERS – ACCESS
FORBIDDEN

Reference Chart: 2044

A recent engineering investigation identified
structural issues and safety concerns with both the
East and West piers at Port Dalhousie. In light of
the inspection findings, the Department of Fisheries
and Oceans is taking action to protect the safety of
the public by prohibiting vessel, vehicular, and
pedestrian access to the piers.

Vessels can still safely navigate the waters
surrounding the piers, but will be unable to moor at
the piers. The City of St. Catharines will
accommodate boaters as possible at other local
wharves.

Mariners are advised that offshore exploration
and exploitation vessels may be conducting drilling
operations in the following areas:

Gulf of
St. Lawrence

NOTE: Mariners are advised to obtain up-to-date
position reports on drilling vessels and production
installations before entering an area of exploration
and exploitation. This information is available by
contacting, as appropriate, ECAREG CANADA, NORDREG
CANADA or CVTS OFFSHORE via any Marine Communications
and Traffic Services Centre (MCTS).

*303(T) STRAIT OF CANSO – 2016 AND 2017, REDUCED
OPERATIONAL SEASON

Reference Chart: 4302

Mariners are advised that, due to extensive
maintenance requirements to the causeway swing
bridge, the Canso Canal will have a reduced
operational season for the next two years. For the
2016 and 2017 navigation seasons, the Canso Canal
will operate according to the following
schedule:

*819(T) AUTOMATIC IDENTIFICATION SYSTEM (AIS)

AIS Application-Specific Messages (ASM) and AIS AtoN

Mariners are advised that the Canadian Coast Guard will perform a test of AIS Application-Specific Messages (AIS-
ASM) on the Pacific Coast from the Sand Heads meteorological/hydrological station: 49°06’21’’N 123°18’12’’W, and
may extend this testing to other stations in the coming months. The test will start at the end of August and consist of
broadcasting meteorological/hydrological (MET/HYDRO) data through AIS binary “Message 8”.

Although AIS was originally developed as a means for positive identification and tracking of ships, it includes
functionalities to transmit binary messages such as MET/HYDRO information and other types of data. These additional
functionalities of AIS may be useful to mariners to assist in onboard voyage planning.

Ships need to be equipped with a proper Class “A” AIS device for the accurate onboard display of AIS message. The
IMO mandatory carriage requirement for the Class “A” AIS display1is the Minimum Keyboard Display (MKD) which
displays the binary data in an alphanumeric form. However, as there is no current requirement for the MKD to be
capable of decoding all AIS binary messages, the display and use of the ASM information may require additional
hardware and/or software2 .

AIS Aids to Navigation (AtoN)

The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) defines an AtoN as:
‘a device or system external to vessels that is designed and operated to enhance the safe and efficient navigation of vessels and/or vessel traffic’.3

The primary purpose of an AIS AtoN Station is to promote and enhance safety and efficiency of navigation by one or more of the following:

Providing a positive and all-weather means of identification;

Complementing existing services (e.g. RACONS) from AtoN;

Transmitting accurate positions of floating AtoN;

Indicating if a floating AtoN is off position (monitoring the status of an AtoN);

Marking or delineating tracks, routes, areas, and limits;

Marking offshore structures;

Enable timely marking of new hazards (fixed or dynamic) using Virtual AIS AtoN.

The use of AIS within the marine aids to navigation service is accomplished by the broadcasting of the aids to navigation report message “Message 21”.

An AIS AtoN can be implemented in three ways, Real, Synthetic, and Virtual.

Physical/real AIS AtoN: An AIS device which is physically located on the AtoN and transmits “Message 21”.

Monitored: A “Message 21” is transmitted from a nearby AIS base station. The AtoN physically
exists but there is no AIS device on it. A communication link is installed on the AtoN to allow the monitoring of its status.

Predicted : A “Message 21” is transmitted from a nearby AIS base station. The AtoN physically
exists but there is neither an AIS device on it nor a communication link. Status and position of the AtoN cannot be monitored.

Virtual AIS AtoN : A “Message 21” is transmitted from a nearby AIS base station for an AtoN that does
not physically exist. The “Message 21” will clearly identify this as a virtual AIS AtoN.

Displays and Symbology

As the AIS information available to mariners will be dependent on their display system, not not all transmitted information may be displayed.
Mariners are encouraged to install systems that provide AIS overlay on either ECDIS or Radar, or both.

POf those vessels that are AIS equipped the various displays available can range from no display on some Class B units, through to the mandatory Class A MKD,
and to a full ECDIS or Radar overlay. In the absence of an ECDIS or Radar overlay, mariners will not be able to fully utilize the AIS AtoN functionality.
Also note that there is a variance in the information that can be displayed on ECDIS or Radar equipment by the different AIS manufacturers.

The symbology that may be displayed on nautical charts, display systems and the MKD is summarised below.

Nautical Charts
On nautical charts AIS AtoN are indicated by a magenta circle surrounding the existing AtoN symbol and an adjacent legend stating AIS.
The font will be straight for fixed AtoN and italic for floating AtoN.
A physical AIS AtoN provided as an overlay on ECDIS, Radar or other display systems are indicated by a diamond shape with crossed lines at the reported position
of the AtoN. A physical AIS AtoN that is off position will use the same symbol but in red. A virtual AIS AtoN is indicated by a dotted line diamond shape with the
crossed lines at the reported position.
